Abstract
An efficient design of an interleaver is essential to achieve near Shannon capacity performance with turbo codes. The turbo code performance curve can change its slope in low bit error rate (BER) region, if the interleaver is not designed properly. In this paper the design of an interleaver that combines randomization and de-correlation property with regular permutation, and yet guaranties an enlarged minimum distance, is proposed. Our solution to design a deterministic interleaver outperforms the random and semi-random interleavers particularly for the turbo codes with short block length. Distance spectrum distribution and simulation results are presented and compared with well established S -random interleaver.
